Code:
B4X:
Dim SV_FTP As ScrollView
SV_FTP.Initialize(800dip)
SV_FTP.Panel.Initialize("ftp_zugang_panel")
SV_FTP.Panel.LoadLayout("ftp_zugang")

o.k., change, but error remains
(Panel size is unknown.... solved)

B4X:
    Dim SV_FTP As ScrollView
    
    Dim CV As CustomLayoutDialog
    Dim sf As Object = CV.ShowAsync("FTP Zugang", _
                                    Starter.loc.Localize("txt_Save"), _
                                    Starter.loc.Localize("txt_Cancel"),"",Null, False)
        
    Wait For (sf) Dialog_Ready (DialogPanel As Panel)

    SV_FTP.Initialize(800dip)
    SV_FTP.Panel.Initialize("ftp_zugang_panel")

    DialogPanel.AddView(SV_FTP,0,0,100%x,100%y)

    SV_FTP.Panel.LoadLayout("ftp_zugang")

You will need to upload a small project that demonstrates it.
o.k., it will take a time. be note, the Error gets only on Android 4.4 Device (on my Android 9 Device all o.k.)
Edit -> TestFile add


Why aren't you using B4XDialog? It has templates for lists.
I have Create it long before B4X Dialogs start (and it works). Later i have change one Field to B4XFloatTextField, Test on newer Device, works.
Now i see it crash on older Device.

If you are creating an input dialog then check B4XPreferencesDialog.
i use it on other Place. For this its not the right.

"Update"
Test on Android 5.1, works
Test on other Android 4, Crash

Test on Android 4:
- Load a other Layout with B4XFloatTextField on CustomLayoutDialog (direct, no ScrollView), works
- Test with B4X Dialogs, crash (at load to ScrollView)
- Test with ScrollView2D, crash

-> it only Crash on Android 4 when load on ScrollView

Anyone an idea?

You shouldn't initialize the ScrollView inner panel. Remove that line and try again.

remove Line, unfortunately the same error.

b4xfloattextfield_createbitmap (java line: 171)
java.lang.IllegalArgumentException: width and height must be > 0
.......

Line 168 to 171 from Java File:
//BA.debugLineNum = 233;BA.debugLine="Dim c As B4XCanvas";
_c = new anywheresoftware.b4a.objects.B4XCanvas();
//BA.debugLineNum = 234;BA.debugLine="c.Initialize(p)";
_c.Initialize(_p);
